Gold was discovered earlyand is highly prized for its

nonreactive properties,its also extremely dense

and highly malleable

Tungsten is usedfor light bulb

Osmium, the hardestmetal, used in antique phonograph needles,

and spent uranium used in armor-piercingprojectiles because ofboth its hardness and

its extreme density
